Explore the future of pneumatics. Our blog offers expert insights, technical guides, and industry trends to help you innovate and optimize your automation systems.
A rodless cylinder is a space-saving pneumatic actuator that generates linear motion without an external piston rod, using advanced internal mechanisms like magnetic coupling, cable systems, or band technology to transfer force directly to an external carriage.
Rodless actuators work by containing the piston inside a sealed cylinder body while transferring linear motion to an external carriage through magnetic coupling, cable systems, or flexible bands, eliminating the need for an external piston rod.
Rodless cylinders are used in packaging machinery, automotive assembly lines, material handling systems, conveyor applications, pick-and-place equipment, and manufacturing processes where space limitations, long strokes, or safety concerns make traditional rod cylinders impractical.
A magnetic rodless cylinder works by using powerful permanent magnets to transfer force through the cylinder wall, with internal magnets attached to the piston and external magnets mounted on a carriage, creating synchronized motion without physical connection through magnetic field coupling.
The main advantages of rodless cylinders include 50% space savings, unlimited stroke lengths, elimination of rod buckling, improved safety without exposed rods, better contamination resistance, higher speeds, and reduced maintenance requirements compared to traditional rod-type cylinders.
